You're correct. Pointers no longer need to be (or can be) typedef-ed separately
from their underlying types. If you want to define an opaque C type (that is,
one which is valid as a pointer type but not as a value type), you can use
C-TYPE: .

I bet this is because of a recent change in string handling in the FFI. While
parameters with a char* pointer type used to be treated specially and would
automatically convert Factor strings to C strings and back, this is no longer
the case. A separate type, c-string, is now used to automatically convert
strings in the FFI. This is discussed in the "C strings" article of the FFI
docs:
http://docs.factorcode.org/content/article-c-strings.html
The fix for odbc will probably be to update some parameters that take char*
parameters (or typedefs thereof) to now take c-string parameters.
